Application filed December 19, 1908, Serial No. 468.279. RenewedDecember 2, 1909. Serial No. 531,069.

To all 114mm "it may concern:

Be it known that l. Josseir Ro'rnciuno, a citizen of the Unite States,and resident of Bayonne, Hudson county, New Jersey, have inventedcertain new and useful Improvements in Valves, of which the following isa specification.

This invention relates to.valves and its novelty consists in theconstruction and adaptation of the parts as will be more fullyhereinafter pointed out.

In the drawings, Figure 1 is a top plan view of the valve body placed ina line of piping; Fig. 2 is a central section on the plane of the line2-2 in Fig. 1; Fi 3 is a transverse section on the plane of the line 3-3in Fig. 2; Fi 4 is a central section on the plane of the line H in Fig.1, Figs. 5 and 0 are p rspectives of the two members of the casing. Fig.7 is a perspective view of the hollow plu and Fig. 8 is a top plan viewof the cylini cr.

' In the drawings, 10 is the valve body preferably made in the form of acylinder and provided on opposite sides with two outwardly extendin rflanges 100, each provided with internal t ireads 101 to receive thethreaded ends of the sections of pipe 102- hetween which the valve isplaced. It is provided with a bottom 103 secured to the cylinder bymeans of screws 104 having hexagonal heads 105 and which screws engagethe threaded apertures 100 formed in the cylinder to receive them. Acentrally arranged upwardly extending positionin pin 107 is secured toor made integral with the bottom 103. The walls of the cylinder adjacent to the flanges 100 are provided with apertures 108, and above andbelow each aperture is an inwardly projecting flange 109. The valve bodyis also provided with a top 110 secured to the cylinder by means ofscrews 111 having hexagonal heads 11:? and which screws engage threadedapertures 113 formed in the cylinder to receive them. The top isprovided with a circular aperture expanded along an are 115 to receive aprojecting fin 304 on the valve flange.

The casing 20 of the valve is formed of two cylindrical segments 200.Each segment has at its lower extremity an inwardly extending plate 201having a central recess 202 adapted to engage the pin 107. It also has anotch or recess 303 at its inner lower edge, and a central longitudinalaperture 204. On the outer surface of each segmentand on eacli'sideofthe aperture 204 are longitudinal outwardly projecting flanges 205adapted to engage the flanges 109 of the valve body.

The plug or key 30 of the valve comprises a hollow cylinder 300 havingtwo diametrically arranged longitudinal apertures 301 and a bottom 302.It is closed atthe to and externally is restricted to form a nec 303adapted to fit within the circular aperture in the top 110 of the valvebody. Projectin radially from the neck is a tin 304 ada he to movewithin the expanded are 115 o the body top 110.

A suitable )acking 10 is arranged between the valve bo y 10 and thecasing 20 except in front of the longitudinal apertures 204 of thelatter. As will be observed its osition is defined by the flanges 205. iove and below these flanges, however, itis .extended in continuous rings401 around the casing. It is also extended in a continuous ring 402above the casing and between the inner surface of the valve body 10 andthe outer surface of the valve plug 30, and is further placed in thespace within the notches or recesses 203 and outside of that portion ofthe valve plug 30 below the apertures 301.

It is obvious that modifications maybe made in the device with the skillof a compotent workman and that the shape, size, form, and to someextent, the arran cmcnt of the parts may be varied withouteparting fromthe principles upon which the invention is based.

Several things are to be noted concerning the valve. In many-valves atpresent in use a packing is interposed between a central plug and acasing or body. Such packing when the plug is rotated is apt to becaught by the edges of the plug aperture and to be subjected to adestructive cutting or shearing action, or to roll up and pull away fromits position. \Yith this valve nothing of that kind can happen. The plugrotates in the casing, one metal surface being opposed to the other andthe packing between the casing and the valve body is between surfaceswhich have no relative circular move ment. The packing between the plugand the valve body above the casing and where till the casing is notchedat the bottom is between surfaces which are smooth and have i noapertures with edges to cause a disruption of such packing. These valvesare intended 1 apertured plug, a removable apertured cas to be used whenfluids at difi'e'eut temperatures are passed through them. The parts,therefore, expand and contract, as such fluids are hot or cold. In thevalves of the present art. the expansion of the plug and casing or bodyusually means a tightening of the,

parts and its contraction a loosening of the parts. This does not occurwith my valve. The segments of the casing are loose with respect to eachother. The packing between the casing and valve body forms a cushionwhich is compressed when the segments move outward and expands when theymove inwardl Butthe plug and easing segments always make together atight fit. The plug is of the same diameter throughout. It is cylindrial and not conical. The surrounding segments are cylindrical. The resultis that the same surfaces are always presented to each other insuccession and there is little or no wear and always a tight fit. Theundue pressure against the plug when its aperture does not register withthe segment apertures and the valve is closed. which is exerted againstthe surface of the plug by a fluid in one of the pipes, simply pressesthe valve away from the segment on that side and toward the oppositesegment. This leaves a slight space between the first segment and theplug and the fluid can leak around the plug and within the se ment untilit reaches the space between the ongitudinal edges of the two segments.It can go on further because the packing between the plug and .valvebody above the casing and at the lower edges of the casing when itssegments are notched prevents it. The valve is readily made, is simplein construction and has the unusual merit. that the plug and easing can,by removing the to bottom bolts, be entirely removed without disturbingthe place of the valve body in the line of pipe.

'What I claim as new is:

the casing and the valve body and the unapertured part of the plug.
